Understanding Fijian health system challenges in the prevention of mother-to-child transmission of HIV services in the three tertiary hospitals in Fiji.

Mother-to-child transmission is the most common route of human immunodeficiency virus transmission in children, which could be prevented with proper treatment and access to care. Health system challenges can impede the effectiveness of prevention of mother-to-child transmission (PMTCT) programmes. We aim to understand the health system challenges to the provision of PMTCT services for pregnant women in three tertiary hospitals in Fiji. Data were collected using in-depth interviews in the three tertiary hospitals and associated health clinics in Fiji between April-May 2013 and February-March 2014. Ethical approvals were obtained. A total of 58 healthcare providers were interviewed including doctors (n = 12), midwives (n = 19), nurses (n = 14), laboratory technicians (n = 5) and counsellors (n = 8). The data were analysed using thematic analysis. We found that the healthcare workers faced a wide range of health system challenges including institutional and human resource challenges. Staff shortage, limited PMTCT training and shortage of supplies were barriers to the quality of PMTCT services. Our findings would be useful in developing strategies to overcome barriers as it would be imperative in improving the quality of PMTCT service provision in Fiji and other similar settings.

Knowledge, Attitude, and Practices Towards COVID-19 Among Pregnant and Postpartum Women in Rural Bangladesh: A Cross-Sectional Study.

OBJECTIVE: To identify knowledge, attitudes, and practices toward COVID-19 among pregnant and postpartum women in rural Bangladesh, and to assess any association with antenatal care attendance (ANC). METHODS: This cross-sectional study was conducted in Northern Bangladesh's Sherpur district with a sample of pregnant and post-partum women enrolled in 'Poriborton', a community-based cluster Randomised Controlled Trial. Knowledge, attitude, and practices toward COVID-19, and any association with antenatal care practices were assessed through face-to-face interviews using a structured questionnaire. Composite measures for knowledge, attitude, and practices of COVID-19 were generated. Specific knowledge on COVID-19 and the association of antenatal care were presented as descriptive statistics. An adjusted odds ratio was used to examine the association between categorical variables. RESULTS: Out of 4835 women, 34.0% correctly identified five or more COVID-19 symptoms, 31.8% knew three or more modes of coronavirus transmission, and 57.0% knew five or more preventive measures. Most (90.1%) had a "more positive attitude to testing" and 65.1% reported adequate practice of preventive measures. Women with adequate knowledge of COVID-19 were more likely to report both a positive attitude to testing (OR:2.96; 95% CI: 1.38-6.37) and adopt adequate practices of preventive measures (OR: 4.30;95% CI: 2.90-6.36). Education and being employed influenced KAP related to COVID-19. Only 14.9% were satisfied with their knowledge of COVID-19. Television was the main source of COVID-19-related specific information. CONCLUSIONS: We found that improved knowledge was associated with positive attitudes and behaviours that lead to the adoption of preventive measures. There was no association with ANC practices as attendance was very low in this region. The findings could be utilised to develop communication strategies for future public health emergencies in similar settings.

Can evidence drive health equity in the COVID-19 pandemic and beyond?

Using scoping review methods, we systematically searched multiple online databases for publications in the first year of the pandemic that proposed pragmatic population or health system-level solutions to health inequities. We found 77 publications with proposed solutions to pandemic-related health inequities. Most were commentaries, letters, or editorials from the USA, offering untested solutions, and no robust evidence on effectiveness. Some of the proposed solutions could unintentionally exacerbate health inequities. We call on health policymakers to co-create, co-design, and co-produce equity-focussed, evidence-based interventions with communities, focussing on those most at risk to protect the population as a whole. Epidemiologists collaborating with people from other relevant disciplines may provide methodological expertise for these processes. As epidemiologists, we must interrogate our own methods to avoid propagating any unscientific biases we may hold. Epidemiology must be used to address, and never exacerbate, health inequities-in the pandemic and beyond.

Perinatal depression screening in community pharmacy: Exploring pharmacists' roles, training and resource needs using content analysis.

BACKGROUND: Perinatal depression (PND) screening is often recommended in primary care settings, which includes the community pharmacy setting. However, there is limited research exploring pharmacists' perspectives on their roles in screening for perinatal mental illness. AIM: This study aimed to explore pharmacists' views of pharmacists' roles in PND screening, as well as training and resource needs for PND screening in community pharmacy settings. METHOD: A questionnaire including three open-ended questions focusing on pharmacists' perspectives of their role in PND screening, their training, and resource needs in this area, was disseminated to pharmacists across Australia via professional organisations and social media. Each open-ended question was separately analysed by inductive content analysis. Subcategories were deductively mapped to the Theoretical Framework of Acceptability. RESULTS: Responses (N = 149) from the first open-ended question about pharmacists' roles in PND screening resulted in three categories (PND screening in primary care settings will support the community, community pharmacy environment, and system and policy changes) and ten subcategories. Responses to question two on training needs (n = 148) were categorised as: training content, training length, and training delivery while responses about resource needs (n = 147) fell into three categories: adapting community pharmacy operating structures, pharmacist-specific resources, and consumer-specific resources. CONCLUSION: While some pharmacists were accepting of a role in PND screening due to pharmacists' accessibility and positive relationships with consumers, others had concerns regarding whether PND screening was within pharmacists' scope of practice. Further training and resources are needed to facilitate pharmacists' roles in PND screening, referral and care.

Does fetal size affect maternal perception of fetal movements? Evidence from an individual participant data meta-analysis.

INTRODUCTION: Maternal perception of fetal movements during pregnancy are reassuring; however, the perception of a reduction in movements are concerning to women and known to be associated with increased odds of late stillbirth. Prior to full term, little evidence exists to provide guidelines on how to proceed unless there is an immediate risk to the fetus. Increased strength of movement is the most commonly reported perception of women through to full term, but perception of movement is also hypothesized to be influenced by fetal size. The study aimed to assess the pattern of maternal perception of strength and frequency of fetal movement by gestation and customized birthweight quartile in ongoing pregnancies. A further aim was to assess the association of stillbirth to perception of fetal movements stratified by customized birthweight quartile. MATERIAL AND METHODS: This analysis was an individual participant data meta-analyses of five case-control studies investigating factors associated with stillbirth. The dataset included 851 cases of women with late stillbirth (>28 weeks' gestation) and 2257 women with ongoing pregnancies who then had a liveborn infant. RESULTS: The frequency of prioritized fetal movement from 28 weeks' gestation showed a similar pattern for each quartile of birthweight with increased strength being the predominant perception of fetal movement through to full term. The odds of stillbirth associated with reduced fetal movements was increased in all quartiles of customized birthweight centiles but was notably greater in babies in the lowest two quartiles (Q1: adjusted OR: 9.34, 95% CI: 5.43, 16.06 and Q2: adjusted OR: 6.11, 95% CI: 3.11, 11.99). The decreased odds associated with increased strength of movement was present for all customized birthweight quartiles (adjusted OR range: 0.25-0.56). CONCLUSIONS: Increased strength of fetal movements in late pregnancy is a positive finding irrespective of fetal size. However, reduced fetal movements are associated with stillbirth, and more so when the fetus is small.

Characteristics of neonatal herpes simplex central nervous system disease in Australia (1997-2020).

BACKGROUND: Neonatal herpes simplex virus (HSV) central nervous system (CNS) disease can occur in isolation or as part of disseminated infection. We sought to describe neonatal HSV CNS disease in Australia over 24 years. METHODS: Neonates (≤28 days) with confirmed HSV infection, reported prospectively to the Australian Paediatric Surveillance Unit (1997-2020), were evaluated for HSV CNS disease (laboratory confirmation with clinical evidence of encephalitis, e.g., lethargy, seizures, focal signs; and/or abnormalities on neuroimaging or electroencephalogram), and compared with neonates without CNS disease. CNS-restricted disease was compared with CNS-disseminated disease. FINDINGS: Of 195 neonates with HSV disease; 87 (45%) had CNS disease (1.29 cases/100,000 live births per year, 95% CI: 1·04-1·59). Neonates with CNS disease were significantly more likely to be male than neonates without CNS disease (60% versus 39%, OR=2·32, 95% CI 1·29-4·18). Of the neonates with CNS disease, those with CNS-restricted disease (52/87, 60%) presented later than neonates with CNS-disseminated disease (35/87, 40%), (mean 12 versus 6 days). Twenty (23%) neonates with CNS disease died, the majority with CNS-disseminated disease (n = 19). Most neonates received aciclovir therapy (94·3%), however five neonates with unrecognised CNS disseminated disease (diagnosed at autopsy) had not been treated. Survivors of CNS disease were significantly more likely to have adverse neurological sequelae, compared with those without CNS disease (30% versus 4%, OR: 9·60, 95% CI: 2·6-35·0). INTERPRETATION: Male neonates have a higher burden of HSV CNS disease. Despite the use of antiviral agents, morbidity following neonatal HSV CNS disease remains high. Evaluation of adjunctive therapies to improve outcomes is needed.

Explanatory models of stillbirth among bereaved parents in Afghanistan: Implications for stillbirth prevention.

Local perceptions and understanding of the causes of ill health and death can influence health-seeking behaviour and practices in pregnancy. We aimed to understand individual explanatory models for stillbirth in Afghanistan to inform future stillbirth prevention. This was an exploratory qualitative study of 42 semi-structured interviews with women and men whose child was stillborn, community elders, and healthcare providers in Kabul province, Afghanistan between October-November 2017. We used thematic data analysis framing the findings around Kleinman's explanatory framework. Perceived causes of stillbirth were broadly classified into four categories-biomedical, spiritual and supernatural, extrinsic factors, and mental wellbeing. Most respondents attributed stillbirths to multiple categories, and many believed that stillbirths could be prevented. Prevention practices in pregnancy aligned with perceived causes and included engaging self-care, religious rituals, superstitious practices and imposing social restrictions. Symptoms preceding the stillbirth included both physical and non-physical symptoms or no symptoms at all. The impacts of stillbirth concerned psychological effects and grief, the physical effect on women's health, and social implications for women and how their communities perceive them. Our findings show that local explanations for stillbirth vary and need to be taken into consideration when developing health education messages for stillbirth prevention. The overarching belief that stillbirth was preventable is encouraging and offers opportunities for health education. Such messages should emphasise the importance of care-seeking for problems and should be delivered at all levels in the community. Community engagement will be important to dispel misinformation around pregnancy loss and reduce social stigma.

Risk factors for late preterm and term stillbirth: A secondary analysis of an individual participant data meta-analysis.

OBJECTIVE: Identify independent and novel risk factors for late-preterm (28-36 weeks) and term (≥37 weeks) stillbirth and explore development of a risk-prediction model. DESIGN: Secondary analysis of an Individual Participant Data (IPD) meta-analysis investigating modifiable stillbirth risk factors. SETTING: An IPD database from five case-control studies in New Zealand, Australia, the UK and an international online study. POPULATION: Women with late-stillbirth (cases, n = 851), and ongoing singleton pregnancies from 28 weeks' gestation (controls, n = 2257). METHODS: Established and novel risk factors for late-preterm and term stillbirth underwent univariable and multivariable logistic regression modelling with multiple sensitivity analyses. Variables included maternal age, body mass index (BMI), parity, mental health, cigarette smoking, second-hand smoking, antenatal-care utilisation, and detailed fetal movement and sleep variables. MAIN OUTCOME MEASURES: Independent risk factors with adjusted odds ratios (aOR) for late-preterm and term stillbirth. RESULTS: After model building, 575 late-stillbirth cases and 1541 controls from three contributing case-control studies were included. Risk factor estimates from separate multivariable models of late-preterm and term stillbirth were compared. As these were similar, the final model combined all late-stillbirths. The single multivariable model confirmed established demographic risk factors, but additionally showed that fetal movement changes had both increased (decreased frequency) and reduced (hiccoughs, increasing strength, frequency or vigorous fetal movements) aOR of stillbirth. Poor antenatal-care utilisation increased risk while more-than-adequate care was protective. The area-under-the-curve was 0.84 (95% CI 0.82-0.86). CONCLUSIONS: Similarities in risk factors for late-preterm and term stillbirth suggest the same approach for risk-assessment can be applied. Detailed fetal movement assessment and inclusion of antenatal-care utilisation could be valuable in late-stillbirth risk assessment.

Understanding the relationship between the public sector healthcare workers and NGO-based HIV counsellors while providing HIV counselling and testing services to pregnant women: A Qualitative Study in Suva, Fiji.

Human immunodeficiency virus (HIV) counselling and testing plays a significant role in the prevention of mother-to-child transmission of HIV. HIV counselling and testing during pregnancy is an essential gateway for HIV prevention, timely treatment, and care services. Lack of proper counselling could jeopardise the quality of services. This paper aims to understand the relationship between the government employed hospital healthcare workers and the Non-Governmental Organisation based counsellors while providing HIV counselling and testing services to pregnant women attending antenatal clinic in one of the main hospitals in Suva, Fiji. Data were collected via individual, in-depth, interviews held in a single hospital and an associated reproductive health centre in Suva in April-May 2013. A total of 15 healthcare providers including doctors (n = 4), midwives (n = 5), nurses (n = 4), and counsellors (n = 2) were interviewed. The data were analysed using thematic analysis. Ethical approvals were obtained. We found that there was tension between the government employed hospital healthcare workers and the Non-Governmental Organisation based counsellors involved in the provision of HIV counselling and testing services to pregnant women. The predominant causes of tension were poor referral for HIV test counselling, long counselling time, lack of cooperation and conflict due to the differences in counselling approaches. Tension between the government employed hospital healthcare workers and the Non- Governmental Organisation based HIV counsellors appear to be the main challenge to effective provision of HIV test counselling services in the hospital. Ongoing tension between both groups could restrict healthcare workers abilities to provide quality HIV counselling services. Our findings would be useful in developing strategies to overcome tension amongst healthcare workers as it would be an imperative step in providing streamlined HIV counselling services to women attending antenatal clinic in Fiji.

Perinatal Women's Views of Pharmacist-Delivered Perinatal Depression Screening: A Qualitative Study.

Internationally, 20% of women experience perinatal depression (PND). Healthcare providers including general practitioners and midwives are critical in providing PND screening and support; however, the current workforce is unable to meet growing demands for PND care. As accessible and trusted primary healthcare professionals, pharmacists could provide PND care to complement existing services, thereby contributing to early detection and intervention. This study aimed to explore perinatal women's views of community pharmacist-delivered PND screening and care, with a focus on their attitudes towards and acceptability of PND screening implementation in community pharmacy. Semi-structured interviews with women (n = 41) were undertaken, whereby interview data were transcribed verbatim and then inductively and thematically analysed. Five overarching themes emerged; "patient experience with existing PND support and screening services"; "familiarity with pharmacists' roles"; "pharmacist visibility in PND screening care"; "patient-pharmacist relationships" and "factors influencing service accessibility". Themes and subthemes were mapped to the Consolidated Framework for Implementation Research. Findings highlight participants' generally positive attitudes towards community pharmacist-delivered PND screening and care, and the potential acceptability of such services provided pharmacists are trained and referral pathways are established. Addressing perceived barriers and facilitators would allow community pharmacist-delivered PND screening and care to support existing PND care models.

The Impact of Antenatal Balanced Plate Nutrition Education for Pregnant Women on Birth Weight: A Cluster Randomised Controlled Trial in Rural Bangladesh.

Low birth weight (LBW) is a global public health problem with the highest prevalence in South Asia. It is strongly associated with maternal undernutrition. In South Asia, intra-household food distribution is inequitable, with lower dietary adequacy in women. Evidence that nutrition education improves diet during pregnancy and reduces LBW is weak. We assessed the impact of nutrition education for pregnant women on birth weight in rural Bangladesh. We conducted a parallel, two-arm, cluster-randomised controlled trial, with 36 clusters allocated equally to intervention (n = 445) or standard care (n = 448). From their first trimester until delivery, intervention participants received education about eating balanced meals to meet daily dietary requirements with diverse food groups. The primary outcome of mean birth weight was 127.5 g higher in the intervention compared to control women, and the intervention reduced the risk of LBW by 57%. Post hoc analyses showed a significantly higher birth weight and a greater reduction in LBW amongst adolescent mothers. The mean number of food groups consumed was significantly higher in the intervention from the third month of pregnancy than in the control. A community-based balanced plate nutrition education intervention effectively increased mean birth weight and reduced LBW, and improved dietary diversity in rural Bangladeshi women.

Iron and Folic Acid Supplementation in Pregnancy: Findings from the Baseline Assessment of a Maternal Nutrition Service Programme in Bangladesh.

Effective coverage of antenatal iron and folic acid (IFA) supplementation is important to prevent adverse maternal and newborn health outcomes. We interviewed 2572 women from two rural districts in Bangladesh who had a live birth in the preceding six months. We analysed the number of IFA tablets received and consumed during pregnancy and examined the factors influencing IFA consumption by multiple linear regression and user adherence-adjusted effective coverage of IFA (consuming ≥180 IFA tablets) by Poisson regression. Overall, about 80% of women consumed IFA supplements in any quantity. About 76% of women received antenatal care at least once, only 8% received ≥180 IFA tablets, and 6% had user adherence-adjusted coverage of antenatal IFA supplementation. Multivariable analysis showed a linear relationship between the number of antenatal care (ANC) visits and the number of IFA supplements consumed, which was modified by the timing of the first ANC visit. Women's education, free IFA, and advice on IFA were also associated with higher IFA consumption. Interventions targeting at least eight ANC contacts, starting early in pregnancy, providing advice on the importance of IFA, and providing IFA supplements in higher quantity at ANC contacts are likely to increase effective coverage of antenatal IFA supplementation.

Perinatal depression screening: a systematic review of recommendations from member countries of the Organisation for Economic Co-operation and Development (OECD).

Perinatal depression (PND) screening recommendations are made by national, state-based and professional organisations; however, there is disagreement regarding screening timing, provider responsible, screening setting, screening tool as well as the follow-up and referral pathways required post-screening. This systematic review aimed to identify, describe and compare PND screening recommendations from member countries of the Organisation for Economic Co-operation and Development (OECD). Publications were identified through systematically searching PubMed, Google and the Guidelines International Network (GIN). Recommendations regarding PND screening endorsement, timing, frequency, responsible provider, tools/assessments and follow-up and referral were extracted. Twenty-one publications, including guidelines, from five countries were included. Most made recommendations in support of PND screening using the Edinburgh Postnatal Depression Scale. Details differed regarding terminology used, as well as frequency of screening, follow-up mechanisms and referral pathways. A broad range of health providers were considered to be responsible for screening. This is the first review to identify and compare PND screening recommendations from OECD member countries; however, only online publications published in English, from five countries were included. Heterogeneity of publication types and inconsistency in definitions rendered quality assessment inappropriate. While most publications generally endorsed PND screening, there are exceptions and the associated details pertaining to the actual conduct of screening vary between and within countries. Developing clear, standardised recommendations based on current evidence is necessary to ensure clarity amongst healthcare providers and a comprehensive approach for the early detection of PND.

Prevalence of, and factors associated with anaemia in children aged 1-3 years in Aceh, Indonesia: A cross-sectional study.

Background: Child anaemia continues to represent a major public health challenge in lower-and-middle income countries. It has serious long-term consequences for child growth and development. In Indonesia, there was a 10% increase in the national prevalence of child anaemia between 2013 and 2018. Aim: This study aims to assess the prevalence of, and factors associated with anaemia among children aged one to three years in eight districts in Aceh Province, Indonesia. Methods: A cross-sectional study was conducted on a sample of 1148 mother-child dyads aged one to three years between November and December 2018. The sampling process involved a three-stage cluster sampling design using the probability proportionate to size methodology. Anaemia status was determined using haemoglobin level (Hb < 11.0 g/dL). Data were analysed using multivariable logistic regression to estimate adjusted odds ratios (aOR) and their 95% confidence intervals (95% CI) for associated factors. Results: The overall prevalence of anaemia was 76.1% (869/1142). 44.7% (510/1142) and 28.6% (327/1142) had moderate and mild anaemia, respectively. Child aged 12-24 months (aOR: 2.00, 95% CI: 1.26-3.17), not receiving routine immunisation (aOR: 2.62, 95% CI: 1.34-5.10), and maternal anaemia (aOR: 2.15, 95% CI: 1.59-2.90) were significantly associated with anaemia. Conclusion: The prevalence of anaemia among the children in this study was high, and was associated with child age, immunisation status, and maternal anaemia. These findings provide further insight into anaemia as a public health issue at a sub-national level in Indonesia and for development of targeted programmes to address associated risk factors of child anaemia.

Reducing household air pollution exposure to improve early child growth and development; a randomized control trial protocol for the "Poriborton-Extension: The CHANge trial".

BACKGROUND: Globally, household air pollution (HAP) is a leading environmental cause of morbidity and mortality. Our trial aims to assess the impact of liquefied petroleum gas (LPG) for cooking to reduce household air pollution exposure on child health outcomes, compared to usual cooking practices in Bangladesh. The primary aim is to evaluate if reduced exposure to HAP through the provision of LPG for cooking from early gestation through to age 2 improves child anthropometry, health, and neuro-cognitive developmental outcomes, compared to children exposed to emissions from usual practice. METHODS: Two-arm parallel cluster randomized controlled trial (cCRT). We will extend the intervention and follow-up of our existing "Poriborton" trial. In a subset of the original surviving participants, we will supply LPG cylinders and LPG stoves (intervention) compared to usual cooking practices and extend the follow-up to 24 months of age. The expected final sample size, for both (intervention and control) is 1854 children with follow-up to 2 years of age available for analysis. DISCUSSION: This trial will answer important research gaps related to HAP and child health and neuro-cognitive developmental outcomes. This evidence will help to understand the impact of a HAP intervention on child health to inform policies for the adoption of clean fuel in Bangladesh and other similar settings. TRIAL REGISTRATION: The Poriborton: Change trial: Household Air Pollution and Perinatal and early Neonatal mortality is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12618001214224, original trial registered on 19th July 2018, extension approved on 23rd June 2021. www.anzctr.org.au .

The effect of electronic job aid assisted one-to-one counselling to support exclusive breastfeeding among 0-5-month-old infants in rural Bangladesh.

Exclusive breastfeeding (EBF) for the first 6 months has established benefits, yet had slow improvements globally. Little is known about electronic job aid-assisted counselling to support EBF. As a secondary outcome of a cluster randomized controlled trial in Bangladesh, we assessed the effect of electronic job aid-supported nutrition counselling and practical demonstration on EBF. We randomized pregnant women to one of five study arms in the trial and followed mother-child dyads until 2 years of age. Community health workers (CHWs) provided breastfeeding counselling with or without prenatal and complementary nutrient supplements in all four intervention arms. The comparison arm continued with the usual practice where mothers could receive nutrition counselling at routine antenatal and postnatal care, and during careseeking for childhood illnesses. We assessed breastfeeding indicators at birth and monthly until the child was 6 months old, in both intervention and comparison arms. To evaluate the effect of nutrition counselling on breastfeeding, we combined all four intervention arms and compared them with the comparison arm. Intervention newborns had half the risk (relative risk [RR]: 0.54, 95% confidence interval [CI]: 0.39, 0.76) of receiving prelacteal feeds than those in the comparison arm. EBF declined steeply in the comparison arm after 3 months of age. EBF was 16% higher in the intervention than the comparison arm at 4 months (RR: 1.16, 95% CI: 1.08, 1.23) and 22% higher at 5 months of age (RR: 1.22, 95% CI: 1.12, 1.33). Maternal background and household characteristics did not modify the intervention effect, and we observed no difference in EBF among caesarean versus vaginal births. Breastfeeding counselling and practical demonstration using an electronic job aid by CHWs are promising interventions to improve EBF and are scalable into existing community-based programmes.

Risk factors of paternal postnatal depression in Pakistan: Findings from an urban sample.

Paternal postnatal depression is an emerging public health concern, with negative outcomes for men, their partners, and the newborn. There is a dearth of data on paternal postnatal depression in lower-middle-income countries like Pakistan. This study aimed to identify risk factors of postnatal depression in Pakistani men. Men who consented to this cross-sectional study completed a questionnaire that included sociodemographic information and Urdu translated versions of the Edinburgh Postnatal Depression Scale (EPDS) and the Pittsburgh Sleep Quality Index, 10-12 weeks postpartum. Descriptive analyses for the sociodemographic variables were calculated. Univariate analyses were conducted to calculate the relative risk and 95% confidence interval of the independent variables with an EPDS score of >10. Multivariate binary logistic regression models were performed for risk factors of paternal postnatal depression. Fifty-one questionnaires were analyzed and 23.5% of the participants scored more than 10 on the EPDS. Spouse's EPDS score > 12, and own sleep disturbance were risk factors of paternal postnatal depression in Pakistani men. There is an imminent need to incorporate fathers in the existing and future perinatal mental health programs in Pakistan.

Protocol for a cluster randomised controlled trial of LPG cookstoves compared to usual cooking practices to reduce perinatal mortality and morbidity in rural Bangladesh called Poriborton: the CHANge trial.

BACKGROUND: Household air pollution is a leading health risk for global morbidity and mortality and a major health risk in South Asia. However, there are no prospective investigations of the impact of household air pollution on perinatal morbidity and mortality. Our trial aims to assess the impact of liquefied petroleum gas (LPG) for cooking to reduce household air pollution exposure on perinatal morbidity and mortality compared to usual cooking practices in Bangladesh. HYPOTHESIS: In a community-based cluster randomised controlled trial of pregnant women cooking with LPG throughout pregnancy, perinatal mortality will be reduced by 35% compared with usual cooking practices in a rural community in Bangladesh. METHODS: A two-arm community-based cluster randomised controlled trial will be conducted in the Sherpur district, Bangladesh. In the intervention arm, pregnant women receive an LPG cookstove and LPG in cylinders supplied throughout pregnancy until birth. In the control or usual practice arm, pregnant women continue their usual cooking practices, predominately traditional stoves with biomass fuel. Eligible women are pregnant women with a gestational age of 40-120 days, aged between 15 and 49 years, and permanent residents of the study area. The primary outcome is the difference in perinatal mortality between the LPG arm and the usual cooking arm. Secondary outcomes include (i) preterm birth and low birth weight, (ii) personal level exposure to household air pollution, (iii) satisfaction and acceptability of the LPG stove and stove use, and (iv) cost-effectiveness and cost-utility in reducing perinatal morbidity and mortality. We follow up all women and infants to 45 days after the birth. Personal exposure to household air pollution is assessed at three-time points in a sub-sample of the study population using the MicroPEM™. The total required sample size is 4944 pregnant women. DISCUSSION: This trial will produce evidence of the effectiveness of reduced exposure to household air pollution through LPG cooking to reduce perinatal morbidity and mortality compared to usual cooking practices. This evidence will inform policies for the adoption of clean fuel in Bangladesh and other similar settings. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ACTRN12618001214224 .

The long-term burden of congenital cytomegalovirus: Hospitalisation and mortality in a population-based matched cohort study.

AIM: Congenital cytomegalovirus (cCMV) infection can result in considerable morbidity and mortality. However, the impact of cCMV on health system utilisation beyond infancy is poorly defined. Here we sought to describe the burden of cCMV health service use and mortality using linked population-based datasets. METHODS: The design was a matched cohort study using record-linked administrative datasets. Participants included all children aged 0-15 years identified through the New South Wales (NSW), Australia, Admitted Patient Data Collection who were hospitalised with an admission code for cCMV infection between 2001 and 2011. Participants were then matched by age, sex and birth postcode quintile using Socio-Economic Indexes for Area, to children randomly selected from the NSW Perinatal Data Collection, excluding those with central nervous system infections or cerebral palsy. We calculated rate ratios (RR) for hospital admissions adjusted for preterm birth, the median length of stay, cost weights of admission and odds ratio (OR) for deaths. RESULTS: There were 130 children with cCMV matched to 2672 children. Neonates (aged <1 month) with cCMV had twice the rate of admissions (RR 2.4 95%CI 2.0, 2.8) and children aged ≥ 5yr to < 15yrs with cCMV almost eight times the rate of admissions (RR 7.8 95%CI 5.1, 11.5). Children with cCMV had significantly higher cost weights of admissions and an increased risk of mortality (OR 18.4 95%CI 7.8, 43.6). CONCLUSION: Throughout childhood, children with cCMV had higher rates of hospital admissions, higher admission cost weights and an increased risk of mortality compared with matched peers without cCMV.
